Biology Directional Terms

As we begin to work with specimens, my students are learning their biological directional terms. Working with these terms will clarify instructions for external anatomy labs and measurements. Each student drew an animal, switched white boards, and then labeled the directional terms on it.

Anterior refers to the front of the animal, meaning ‘before’ in Latin. Posterior refers to the back of the animal, meaning ‘after’ in Latin. Dorsal refers to the upper side or back of the specimen. In Latin, dorsum means ‘back.’ Ventral means ‘belly’ in Latin.
